Replacements should always be done
by two persons, with one person acting

The machine must be elevated before
replacing the rubber crawler belts. Be
careful not to allow the machine to fall
when replacing crawler belts, since this
could be extremely dangerous. Slowly
lower the machine on the side of the
idler and remove the crawler belts.
This machine uses a hydraulic cylinder to
adjust the tension of the crawler belts. Note
that it is not necessary to regularly perform
adjustments of the tension of the belt itself.
IMPORTANT: During the replacement
procedure, only start the engine when
raising and lowering the machine body.
Otherwise, always keep the engine off.
IMPORTANT: When the travel speed
switch is set to the 2nd speed side while
the engine is running, the tensioning
cylinder rods extend and the crawlers are
tightened.
Removal
1. Start the engine and raise the machine
body with the hoe attachment and dozer
blade.
2. Stop the engine.
3. Remove the valve covers (1) at the center
of the left and right crawler frames.
4. Loosen the lock plate (2) counterclockwise.
5. Turn the valve handle (3) counterclockwise
to loosen the tension of the crawler.
6. Once the crawler is completely loose,
tighten the valve handle (3).
7. Tighten the lock plate (2).
8. Do the same for the other side.
9. Slowly lower the dozer blade side of the
machine body, by the dozer blade lever.
(Do not start the engine.)
